We have successfully shipped to SA before. If they refuse the package, it will bounce back to us and we will separate the xNT chip from the injector and re-ship it for free. You can then take it to any body piercing shop and ask them to use a 10g needle and taper to perform the installation.

I know that Argentinian customs are particularly nasty, so I'll be flying to Chile, where customs is a little more lax. I already know of at least one pro piercer who has shown interest in RFID implants, so hopefully I'll have news soon!
